Dataset specification
- Title: GeoBasis Disko - Meteorology - AWS3-Meteorology
- Description: The automatic weather station AWS3 was installed in July 2013. It is located in the southern part of Blæsedalen (90 meter above sea level) in an open gently rolling area. It is a relatively dry location. A thin layer of soil with low heath vegetation/dwarf shrubs covers the bedrock. The station is running West Greenland Standard Time (UTC-3). The AWS3-Meteorology file holds the following parameters (Air temperature, Relative humidity, Wind (speed and direction) Liquid precipitation and PAR). The rain gauge was installed in August 2014. Find more data from AWS3 under Soil (AWS3-SoilMoisture, AWS3-SoilTemperature). Soil temperatures are only available after July 2018. All data are logged by 30-minute intervals using a CR1000 datalogger from Campbell Scientific. Meteorology:Meteorology GeoBasis Disko:The GeoBasis monitoring programme focuses on selected abiotic characteristics in order to describe the state of Greenlandic terrestrial environments and their potential feedback effects in a changing climate. Monitored plot data is up-scaled to a landscape level and is used to improve ecosystem models to be able to quantify these feedback mechanisms. The GeoBasis programme provides an active response to recommendations in international assessments such as ACIA and SWIPA; and is continuously being adapted based on AMAP and other international founded recommendations. Furthermore, the GeoBasis programme is directly involved in several international networks and research projects (e.g. the Circumpolar Active Layer Monitoring (CALM) programme, the Nordic Centre of Excellence DEFROST, the Danish Centre of Excellence CENPERM, the EU-projects PAGE21 and INTERACT, and the Arctic Research Centre at Aarhus University). The GeoBasis programme is divided into a number of sub-groups, including:
